DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] According to the diagnosis system of the invention, an inspector brings a small inspection unit to various sites, and inspects objects by installing the small inspection unit. The small inspection unit attachable to a portable information processor (hereinafter called a portable personal computer) and the portable personal computer have a communication unit. The inspector transmits the inspection data collected by the small inspection unit to the host computer in the office of support center through the communication unit of the portable personal computer. The host computer in the office diagnoses the device or the state of internal communication line based on the collected inspection data and inspection reference data stored in the host computer. The host computer transmits the result of diagnosis, and information necessary for maintenance, checking, adjustment or repair to the portable personal computer at the site of inspection by on-line process. As a result, the inspector can react promptly at the site. This system may be developed so that a further advanced service may be presented.

[0019] That is, according to the inspection request or reserved periodic diagnosis schedule, the host computer of the support center sends necessary information to the portable personal computer connected to the host computer by wireless or wired network. The host computer instructs an inspector available in schedule and close to the customer to inspect the object by sending the way to the customer's place, item of inspection, inspection unit to be used, adjustment specification, and parts to be replaced. Thus, the inspector can rush to the customer to satisfy the request adequately.

[0020] If the inspection at the site can be done sufficiently only with the inspection data stored in the portable personal computer, the inspector can inspect alone with the portable personal computer and the inspection unit only. If insufficient, the inspector installs the wireless communication unit or Internet circuit in the portable personal computer, and receives supports from the support center while communicating with the host computer. The inspector can receive the additional inspection data from the host computer, and inspects again. Further, the inspector transmits the raw data collected to the host computer, and can request diagnosis by the diagnosis program. The inspector also may convert the raw data collected into a format easy to analyze in the portable personal computer, and transmit the processed data to the computer of the professional person in charge to request analysis. Thus, the inspector can inspect adequately and promptly at the customer site depending on the status of the inspection object.

[0021] As a result of inspection, if maintenance parts are needed, the stock and their delivery term of maintenance parts can be checked from the portable personal computer through the host computer and network. The host computer orders maintenance parts and specifies the destination and date of shipping of the parts, and immediately returns the result to the portable personal computer at the site. Thus, the inspector at the site can immediately inform the customer of the delivery period of parts, completion date of maintenance or repair, and expenses.

[0022] Moreover, if the inspector replaces the inspection unit with a credit information reader, the payment can be settled on the spot by the customer's credit card, prepaid card, IC card, various member card or cash card, as well as a new customer's information can be also registered at the site.

[0023] Embodiments of the invention are explained below by referring to the accompanying drawings.

[0036] In the support center system 104 in FIG. 3, a CD-ROM (or DVD-ROM) 131 records inspection data necessary for inspection. Instead of the CD-ROM (or DVD-ROM) 131, HDD, CD-R, CD-RW, CD-RAM, DVD-RAM, and other recording media can be used. The latest test data 421 is recorded in an inspection database 42.

[0037] The inspector preliminarily installs the CD-ROM 131 in the portable personal computer 11, and, if necessary, can download the latest test data 421 in the portable personal computer 11 through the network 6. The inspector brings this portable personal computer 11 to the site of inspection. Thus, at the site, the inspector may connect the inspection unit 21 with the line exchange unit 5 to be inspected, and can finish the diagnosis alone only by using the portable personal computer 11 without communicating with the host computer 4 through the wireless communication unit 31.

[0038] However, as a result of diagnosis of the line exchange unit 5, the inspector may not find the cause due to abnormality in frequency characteristic or the like, or the inspector may need maintenance parts. In such case, the inspector connects the portable personal computer 11 to the host computer 4 by way of the wireless communication unit 31 to request on-line diagnosis for analysis. The inspector can also order maintenance parts to a parts center 102 through the support center 104.

[0039] When on-line diagnosis is requested in the office 101, an on-line processing unit 422 writes the transmitted data on a web disk 65 on the network 6. Professional inspectors waiting at the personal computers 61, 62, and 63 perform on-line diagnosis by analyzing the data written in the web disk 65.

[0040]FIG. 4 is an explanatory diagram of emulation processing in the invention. In FIG. 4, the same reference numerals as in FIG. 1, FIG. 2, and FIG. 3 are not explained again.

[0041] In FIG. 4, the communication line exchange unit 5 is the object of inspection, and it is connected to an inspection unit 21 of a portable personal computer 11 having an emulation input mode. The inspection unit 21 comprises a waveform processing unit 211 for analyzing the waveform, an A/D and D/A converter 214 for converting input and output data of the line exchange unit 5, a buffer 213 for storing the data from the waveform processing unit 211 and the A/D and D/A converter 214, a timing unit 212 for controlling the operation timing of the waveform processing unit 211, the A/D and D/A converter 214 and buffer unit 213, and an emulation unit 215 for expanding the function so that the host computer 4 can exchange data directly with the A/D-D/A converter 214 through the buffer 213. Thus, the host computer 4 make the portable personal computer 11 at the site transmit the raw inspection data from the inspection unit 21 to the host computer 4.

[0042] Generally, the waveform processing unit 211 processes inspection data into frequency characteristic data or the like. The wireless communication unit 31 transmits the frequency characteristic data to the host computer 4. The on-line processing unit 422 of the host computer 4 stores the transmitted frequency characteristic data in the web disk 65. The professional inspector at one of the personal computer 61 to 63 downloads the frequency characteristic data stored in the web disk 65 through the network 6, so as to makes on-line diagnosis.

[0043] At this time, the professional inspector may require not only the frequency characteristic data acquired, but also the past inspection data or the raw inspection data before processing into frequency characteristic data for making diagnosis.

[0044] In this case, the professional inspector in the office 101 request to the portable personal computer 11 at the site through the host computer 4, to transmit the raw inspection data from the inspection unit 21. As a result, the emulation unit 215 in portable personal computer 11 at the site transmits the data of the A/D and D/A converter 214 directly to the host computer 4 through the buffer unit 213. Thus, each professional inspector using the respective personal computer 61 to 63 in the office 101 can exchange inspection data directly with the line exchange unit 5 at the site. By providing the on-line processing unit 422 of the host computer 4 with the waveform processing unit 4221 for processing inspection data into frequency characteristic data, the professional inspector can make more detailed, precise and specific on-line diagnosis in the office 101 than at the site, by using both the raw inspection data directly fetched from the site of inspection and the processed frequency characteristic data.

[0045] In the remote diagnosis system explained in FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the inspection object is the communication line exchange unit 5. However the remote diagnosis system of the invention may be also applied to other such inspection objects as electric household appliance, mobile electronic appliances, power device, and other electric and electronic products. The procedure in such applications is same as in the foregoing embodiments, and the explanation is omitted.
